•
The cabinet provides enough stability so that system components pass Telcordia
GR-63-CORE Section 5.4.2 regulations for operational vibration.
•
To prevent stray voltages, all components are grounded together through the
vertical mounting rails to the cabinet frame, and then to ground and also to local
building ground. To ensure signal quality, use a grounding cable provided by
Stratus for local building ground.
•
There is a plan for maintaining cables and wires to the cabinet by either running
them under the floor or placing them overhead in a power bus.
•
Air flows through the cabinet from front to back.
•
Air does not recirculate within the cabinet.
•
Filler panels cover any unused rack space to prevent air recirculation.
•
Vents are evenly distributed on the front and rear doors and comprise at least 63%
of the surface area.
N O T E
If your cabinet does not have vented front and rear doors,
you can remove the doors from the cabinet while the
ftServer system is operating.
